asv quickstart not producing default config

at least on my machine with py27 and osx 10.9 - same for asv help:

`➜  tardis git:(master) ✗ asv quickstart
Traceback (most recent call last):
  File "/Users/wkerzend/Library/Python/2.7/bin/asv", line 9, in <module>
    load_entry_point('asv==0.1', 'console_scripts', 'asv')()
  File "/Users/wkerzend/Library/Python/2.7/lib/python/site-packages/asv-0.1-py2.7.egg/asv/main.py", line 29, in main
    conf = Config.load(args.config)
  File "/Users/wkerzend/Library/Python/2.7/lib/python/site-packages/asv-0.1-py2.7.egg/asv/config.py", line 44, in load
    raise RuntimeError("Config file {0} not found.".format(path))
RuntimeError: Config file asv.conf.json not found.`

great tool though - looking forward to using it.
